Anthem Demo version: Latest on 1st Feb 2019
When game loads to the server connection screen some post process looks broken. Over the usual expected picture the lot of white with some fragments around javelin is shown and then amount of white is increasing until it fill the screen to the all white.
EDIT: Screenshot added.
Same with Vega56. So far it seems to be an issue with the home screen only. Let's hope 19.2.1/2 will fix it for the release version.
